Dhaka, Nov 16 (ANI): Shi'ite Muslims took to streets in Bangladesh on Friday; flogged themselves with steel-tipped flails and slashed their bodies with knives to express solidarity with Imam Hussein, the grandson of Prophet Mohammad, observing ‘Ashura’ the 10th day of the Islamic month of Muharram. Imam Hussein was killed by his political rivals along with 72 companions in the 7th century battle of Karbala. Crowd of mourners, men and women came out in droves and observed Ashura. Ashura falls on the tenth day of a 40-day mourning period during the Islamic calendar's first month, Muharram, which commemorates the death of Imam Hussein. Shi'ites express their mourning by crying, flagellating themselves and listening to verses and sermons about how Hussein and his family were martyred.
